On the territory of Ukraine in the wild the most widespread the representatives of the Oxyacanthae Zbl section of the Crataegus L. genus (hawthorn), which has 31 species in the world's flora, 13 species in the Ukrainian flora, 17 species of the flora of the CIS countries. Three species of this section (C. oxyacantha L., C. monogyna Jacq., C. curvisepala Lindm.) are included into the State Pharmacopoeia of Ukraine, and two species (C. oxyacantha L. and C. monogyna Jacq.) - to the European Pharmacopoeia. Aim. Carry out a morphological and taxonomic study of the Oxyacanthae Zbl section by vegetative characteristics. Methods. The mathematical approach (graph analysis method) was used. The system was subjected to 140 morphological vegetative features of the hawthorn sections of the Oxyacanthae Zbl., which grow on the territory of Ukraine and adjacent countries. 2380 positive and negative states of taxonomic signs were analyzed. Results. On the basis of the calculated coefficients of pair affinity were established taxonomic relationships between species of the Oxyacanthae Zbl section. The main group of hawthorns was found which generalizes the morphological characteristics of the section Oxyacanthae Zbl. by vegetative characteristics. Conclusions. For the first time, the morphological and taxonomic study of the Oxyacanthae Zbl section was conducted by vegetative characteristics. It was established that the section was divided into 5 branches, which, in general, correlate with the range of species growth. The basic morphological vegetative features of the section were established
